Taking ‘the rest of it’ on faith
I have heard some theists explain the foundations of their beliefs as follows: ‘Some of what the Bible says is confirmed by evidence. The rest, I take on faith.’
I have always felt that such statements trivialize ‘the rest’ and mask the fact that the relevant parts of the Bible, the parts on which a Christian belief system rests (God’s creatorship, the miracles that authenticated Jesus, the doctrine of salvation, etc.) all have to be taken on faith.
The gospels and Acts are the sources of the essential claims of Christianity. Even if those books were sworn affadavits by people who knew Jesus, it would not be proof of what Jesus did or said; it would only tell us what the authors were willing to swear to.
